Prophet-5 Voice Expansion Card

Prophet-5 Voice Expansion Card


This is a five-voice voice expansion card for the Prophet-5 synthesizer. Installing this into a Prophet-5 expands its total polyphony to ten voices. Paired with OS 2.0, this also gives the Prophet-5 bi-timbral stack and split capability. Layer two sounds simultaneously for thicker, more powerful chords and pads. Or split the keyboard into two independent performance zones and play synth bass in the lower range and leads in the upper range. Installation instructions are here.

Before ordering, update your Prophet-5 to OS version 2.0 or later. Install the OS update, then restart your Prophet-5 and confirm which card it requires by holding down the FACTORY button and pressing PRESET. The Prophet-5 display will show either 1 or 2.

PLEASE NOTE: If your Prophet-5 requires the “Type 1” card you will need to contact our support department for some additional details before ordering. To contact support please visit our support page.

If your Prophet-5 requires a “Type 2” card, please select it from the dropdown menu above.
